Description
Technical field
The present invention relates to the mammography equipment for detecting malignant cell in breast, it comprises x-ray source and cooperates the X-ray detector of the radioscopic image providing described breast with this x-ray source, also comprise by by breast by being pressed in the oar that described X-ray detector makes breast flatten, wherein adopt at least one sensor to measure for determining that oar is by the parameter being pressed in supramammary pressure, and wherein provide according to being applied to the control system that supramammary pressure controls the actuating of this oar.The object flattened for making breast and be pressed on X-ray detector by breast with oar, this is expect for the suitable radioscopic image obtaining breast.
Background technology
From US-B-7,656, the mammography equipment as described in preorder can be known in 993.In the mammography equipment that this is known, blade root is shaped according to the curve of breast, and described oar comprise multiple can pressure measured by some pressure transducers and by the element independently moved and control, thus provide expectation pressure when taking into full account breast physical features to breast.
A shortcoming of known mammography equipment is that it advises applying the distribution of uneven pressure to breast to improve the quality of x-ray imaging.But what usually understand in prior art is need to apply uniform pressure to the breast that flattens, and allows the X-ray of the less dosage of application thus and provides more good picture quality.
Summary of the invention
Therefore the first object of the present invention especially will take into account those to be considered to the parameter relevant to mammographic quality.Know these parameters and take into account these parameters and be considered to improve the establishment whether existed malignant cell.
Another object of the present invention is to improve known mammography equipment, avoids pressurization unnecessary to breast in x-ray imaging process thus.
Another object of the present invention is the performance strengthening mammography equipment, reliably to detect the malignant cell in breast tissue.
Another object is to provide the existing methodical replacement method utilizing the known method of mammography, the possibility being used to determine further to be existed by the malignant cell of mammography equipment Inspection of wherein pressurizeing.
These and other objects of the present invention become obvious by following discloses, and they have the feature of the mammography equipment of the present invention that claims limit at least partly.
A first aspect of the present invention, mammography equipment has contact area measuring unit, for measuring the contact area between breast and oar.In mammography equipment of the present invention, oar is preferably manufactured by entirety, namely one-body molded, does not at least have according to US-B-7,656, a series of contiguous oar element that can move separately and control of the prior art of 993.
Contact area measuring unit can use in two kinds of patterns.In one embodiment, at least one sensor is used for measurement and is applied to supramammary power, and this power provides together with contact area and is applied to supramammary average pressure.This average pressure can be controlled in the level place established in advance subsequently, avoids unnecessary in imaging process and evitable pain thus.
And the contact area that records between the breast caused by breast compression and oar can use in the lump with the pressure level of establishing in advance, to calculate and to apply specific average pressing pressure, and do not rely on the size of individual breast.Knowing and controlling this specific average pressing pressure makes mammography operate standardization better, and it improves examination precision while avoiding just by the evitable pain of the people of examination.Diastolic pressure magnitude average pressing pressure under many circumstances (particularly for micromazia) avoid excessive discomfort.
If at least one sensor is used for directly measuring being applied to supramammary pressure instead of power in aforementioned applications, this is for being possible in the advantageous embodiment be discussed later.
Preferably, contact area measuring unit comprises Optical devices.So it can be measured the contact area between breast and oar and can not disturb x-ray imaging.So suitably, Optical devices comprise photographing unit, are preferably CCD camera.
Further aspect of the present invention relates to a kind of like this mammography equipment for detecting malignant cell in breast, it comprises x-ray source and cooperates the X-ray detector of the radioscopic image providing described breast with this x-ray source, and comprise by by breast by being pressed on described X-ray detector with the oar making breast flatten, and comprise the contact area measuring unit of Optical devices (preferably photographing unit), it is for measuring the contact area between breast and oar, and wherein oar is translucent.In such mammography equipment, advantageously oar or be connected to light source with the lamella lucida of separating that oar fits together, wherein said oar or described lamella lucida of separating and described light source are arranged in oar or described plate propagates light, and for once breast tissue contact oar or described plate, from oar and described plate release light on the direction of photographing unit.This provide the very effective and simple mode of one to realize contact area measuring unit, namely by utilizing the so-called frustrated total internal reflection effect when oar (or the plate fitted together with oar) contacts breast at the middle light propagated of oar (or described plate).Light quantity and light depend on from the area that oar (or from described plate separated) spills (locally) pressure be applied to by breast oar or described plate.This phenomenon makes to depend on (locally) pressure becomes possibility further to measure the perfusion of blood capillary in skin of breast, such as, use speckle imaging.
Preferably, oar and/or become by Lexan polycarbonate resin with the plate separated that oar fits together.Lexan is the registered trade mark of Sabic Innovative Plastics company for amorphous engineered thermoplastic, its machinery because of brilliance, optics, electricity and thermal characteristics and famous.Optical characteristics makes material be very suitable for providing effective optical path between contact area measuring unit and breast to be checked.The optical characteristics of polycarbonate resin can also by providing micro-titanium dioxide to it and being further improved.Can also be graphene coated on oar and/or the plate separated, Graphene is famous with the heat conducting excellent performance of its intensity, semi permeability and electricity.
